Ruptured Bronchial Artery Aneurysm Treated With Aortic Stent Graft and Aneurysm Embolization

BACKGROUND

Mediastinal bronchial artery aneurysms are uncommon, with fewer than 40 published case reports. This study objective was to evaluate the short term follow up of two cases ruptured Bronchial Artery Aneurysm (rBAA) treated with aneurysm embolization and subsequent aortic stent graft.

METHODS

Two cases of rBAA were treated with a combination of an aortic stent-graft and aneurysm embolization. With rBAA, aneurysm embolization could be performed with sodium polymannuronate until the aneurysm was almost completely packed. One of the limitations of aneurysm embolization is spontaneous recanalization of previously occluded aneurysm. So a stent-graft was deployed to isolate the feeding artery of the rBAA from the descending aorta. The 3 months follow- up after the procedure included chest or back pain and computed tomographic angiography.

RESULTS

The hospital stays of the 2 cases were 5 and 7 days. Chest or back pain was disappeared. There were no hospital deaths and late deaths. Computed tomographic angiogram showed no recanalization and no hemothorax. These 2 patients have not reported any complications up to now.

CONCLUSION

Aortic stent graft combined with aneurysm embolization is a minimally invasive, effective and safe method for rBAA.

Endovascular treatment of ectopic bronchial artery aneurysm with brachiocephalic artery stent placement and coil embolization: A case report and literature review

BACKGROUND

Bronchial artery aneurysm (BAA) is an uncommon but potentially life-threatening disease, and multiple BAAs are even rarer. Clinically, the tortuous and short neck of a BAA may present significant challenges for invasive intervention.

METHODS

This report describes the detailed process of diagnosis and treatment and includes a literature review of the etiology, clinical presentation, and therapeutic management of BAA.

RESULTS

A rare case of multiple BAAs, with one having an inflow artery arising from the brachiocephalic trunk, was referred to our hospital. The patient was successfully treated with coil embolization and brachiocephalic artery stent placement. In addition, we conducted a literature review involving 63 cases of BAA. BAA was most commonly associated with bronchiectasis and was located predominantly in the mediastinum. There was no significant difference between the diameters of the ruptured aneurysms and those of the nonruptured aneurysms (P = 0.115). Transcatheter arterial embolization was the most commonly adopted technique to treat BAA, while thoracic aortic endovascular repair was selected if the neck between the aneurysm and the aorta was short. Subgroup analysis suggested that patients with > 1 BAA were significantly more likely to be female than male (χ test, P = 0.034).

CONCLUSION

Transcatheter coil embolization combined with stent placement could be a reasonable treatment option for BAAs with a tortuous and short neck. According to our literature review, patients with multiple BAAs display distinctive clinical characteristics compared with patients with a single BAA.
